Kansas Secretary of State Kris Kobach met with President-elect Donald Trump for about 45 minutes on Sunday afternoon.

Trump has been hosting a series of meetings at his private golf club in Bedminster, New Jersey, this weekend as he crafts his cabinet. New Jersey Gov. Chris Christie and former New York City Mayor Rudy Giuliani also met with Trump on Sunday.

Trump greeted Kobach at his door Sunday afternoon and then later walked him out.

According to an account provided by the Trump transition team late Sunday, Trump and Vice President-elect Mike Pence met with Kobach “to discuss border security, international terrorism, and reforming federal bureaucracy.”

If he’s hired, it is likely that Kobach would have some role in the administration related to immigration policy.

Kelly Arnold, the Kansas state Republican chairman, said that Kobach has helped frame the national debate over immigration and said Kobach has given states tools to combat illegal immigration.

“It’s been frustrating for states because it seems like we haven’t had much help from the federal government in tackling illegal immigration,” Arnold said.

Kobach crafted SB 1070, the controversial Arizona law that requires law enforcement officers to demand to see the papers of anyone they suspected of being in the country illegally, a policy that critics have denounced as racial profiling.

He also crafted a Kansas law that requires voters to provide proof of citizenship, such as a birth certificate, when they register to vote.

Both laws have faced numerous legal challenges and portions of them have been struck down in court.

Arnold said that Kobach could now have “a national opportunity” to fight illegal immigration.

“The fact that he’s being considered for a key position in the Trump administration is just a wonderful thing for Kansas,” Arnold said.
